Distribution of weights at normal displacement:
   Armament: 3 tons, 0.9 %
   Machinery: 132 tons, 36.4 %
   Hull, fittings & equipment: 114 tons, 31.5 %
   Fuel, ammunition & stores: 38 tons, 10.5 %
   Miscellaneous weights: 75 tons, 20.7 %

Overall survivability and seakeeping ability:
   Survivability (Non-critical penetrating hits needed to sink ship):
     215 lbs / 98 Kg = 10.4 x 3.5 " / 88 mm shells or 0.2 torpedoes
   Stability (Unstable if below 1.00): 1.13
   Metacentric height 0.5 ft / 0.2 m
   Roll period: 11.2 seconds
   Steadiness   - As gun platform (Average = 50 %): 51 %
         - Recoil effect (Restricted arc if above 1.00): 0.13
   Seaboat quality  (Average = 1.00): 1.40

Hull form characteristics:
   Hull has a flush deck
   Block coefficient: 0.634
   Length to Beam Ratio: 7.00 : 1
   'Natural speed' for length: 11.74 kts
   Power going to wave formation at top speed: 68 %
   Trim (Max stability = 0, Max steadiness = 100): 36
   Bow angle (Positive = bow angles forward): 12.00 degrees
   Stern overhang: 6.56 ft / 2.00 m
   Freeboard (% = measuring location as a percentage of overall length):
      - Stem:      16.40 ft / 5.00 m
      - Forecastle (20 %):   9.19 ft / 2.80 m
      - Mid (50 %):      9.19 ft / 2.80 m
      - Quarterdeck (15 %):   9.19 ft / 2.80 m
      - Stern:      9.19 ft / 2.80 m
      - Average freeboard:   9.76 ft / 2.98 m

Ship space, strength and comments:
   Space   - Hull below water (magazines/engines, low = better): 148.3 %
      - Above water (accommodation/working, high = better): 85.9 %
   Waterplane Area: 2,014 Square feet or 187 Square metres
   Displacement factor (Displacement / loading): 97 %
   Structure weight / hull surface area: 27 lbs/sq ft or 132 Kg/sq metre
   Hull strength (Relative):
      - Cross-sectional: 0.83
      - Longitudinal: 6.76
      - Overall: 1.02
   Hull space for machinery, storage, compartmentation is cramped
   Room for accommodation and workspaces is cramped
   Good seaboat, rides out heavy weather easily

Fitted with minesweeping gear and mine rails. Mission is inshore minesweeping and laying.
